- Thank you for this explaination. It means that in my wide
- area network anyone can steal my software. This is really a serious
- problem for me as I now have a number of LANS connected to mine.
- I have a rich variety of software which I meter but I have no
- way to assure that it is not copied to another server or even
- a workstation. I wonder if I could survive an audit!
- I assume others must think this is a serious problem besides me.
- It may be a DOS limitation but is is a problem none the less.
